Abstract

This project involved two phases, the first of which compiled reviews of recharge and discharge studies that have been undertaken
in Australia. It also involved preliminary identification of the parameters (climate, soils, regolith, near-surface geology,
landforms, vegetation etc.) that determine recharge and discharge rates along with a review of the appropriate scale mapping
approaches available for these parameters. The second phase of the project utilised empirical relationships derived from data
collected in Phase 1 of the project in a decision tree methodology that guides the user to the most appropriate estimate for
recharge/discharge given the data availability.
This report documents the various methods of estimating recharge and/or discharge using specifically developed Excel spreadsheets
and associated input GIS data.
